abstract = {Medulloblastoma (MB) comprises four subtypes of which group
3 MB are the most aggressive. Although overall survival for
MB has improved, the outcome of group 3 MB remains dismal.
C-MYC (MYC) amplification or MYC overexpression which
characterizes group 3 MB is a strong negative prognostic
factor and is frequently associated with metastases and
relapses. We previously reported that MYC expression alone
promotes highly aggressive MB phenotypes, in part via
repression of thrombospondin-1 (TSP-1), a potent tumor
suppressor.In this study, we examined the potential role of
TSP-1 and TSP-1 peptidomimetic ABT-898 in MYC-amplified
human MB cell lines and two distinct murine models of
MYC-driven group 3 MBs.We found that TSP-1 reconstitution
diminished metastases and prolonged survival in orthotopic
xenografts and promoted chemo- and radio-sensitivity via AKT
signaling. Furthermore, we demonstrate that ABT-898 can
recapitulate the effects of TSP-1 expression in MB cells in
vitro and specifically induced apoptosis in murine group 3
MB tumor cells.Our data underscore the importance of TSP-1
as a critical tumor suppressor in MB and highlight TSP-1
peptidomimetics as promising novel therapeutics for the most
lethal subtype of MB.},
